If there’s an argument about whether or not he’s mad or bad one question to ask is what difference that would make.

I remember the arguments over Brevik, I don’t think it went much further than the left and right staking out ideologically convenient positions.

Males do have a tendency to become obsessed, to hold grudges and to seek revenge. That’s genetics. Thankfully there’s various things that mitigate against that. Some of that male behaviour does veer into territory that could be seen as delusional.

There’s going to be a legal argument, to be sure.

As far as relevant generalisations go, there's always `men are from Mars, women are from Venus'. When the book of that title became a best-seller in '92, I was amazed. It seemed that everyone had long known that already, so why spend money to learn what you already know? It revealed the contagious effect of trendy notions: "The book has sold more than 50 million copies, and according to a 1997 report by the book's publisher, HarperCollins, it is the all-time best-selling hardcover nonfiction book."https://en.wikipedia.org/wiki/Men_Are_from_Mars,_Women_Are_from_Venus

But stereotypes are just the superficial manifestation of archetypes. Since we inherited the notion that Mars is the warrior archetype and Venus is the beauty archetype from classical-era Rome, who inherited it from Greece & earlier Mesopotamian civilisations, we can see several millennia of cultural and political tradtion are informing us.

Nowadays we also have evolutionary psychology informing us. Motivations prompting political violence derive from deep within. Explanations deriving from genetic research seem to provide helpful insights into deep human nature, although I still find historical continuity of the archetypes more persuasive. Then we must factor in how the warping effect of a toxic political culture gives males targets for their hostility.

As regards this white male suicide trend, seems a consequence of capitalism turning them into losers, and exit becomes an admission of defeat. Or, if you believe in reincarnation, a transition into trying again in a different temporal and socio-political context.

Neil, I think you might be onto something. The Guardian, which is a reputable news outlet, has reported on a scientific study that supports the idea that male brains are indeed different to female brains.

Male and female brains differ in the connections they form. Most notably, the male brain is generally connected to a penis by various involved systems.

Across the sample, between 0 and 8 per cent of people had “all-male” or “all-female” brains, depending on the definition. “Most people are in the middle,” says Joel.

This means that, averaged across many people, sex differences in brain structure do exist, but an individual brain is likely to be just that: individual, with a mix of features. “There are not two types of brain,” says Joel.

Brains, especially infant brains, are incredibly plastic. Your brain is shaped by the things that happen around you just as much as by your genes. So we teach boys that it's not okay for them to cry, but that it IS okay for them to be angry or 'play rough', because Boys Will Be Boys. And then we say it's not their fault, it's testosterone.

My younger son is trans. For about six months now, he's been injecting testosterone. You know how his behaviour has changed with increasing levels of T? Not one bit.

Alexandra Kautzky-Willer, head of the Gender Medicine Unit at the Medical University of Vienna in Austria, agrees that things aren’t so simple. “There are differences between men and women when you look in large groups, and these are important for diagnosis and treatment,” she says. “But there are always more differences within genders. We always need to look at culture, environment, education and a person’s role in society,” she says.

If a neuroscientist was given someone’s brain without their body or any additional information, they would still probably be able to guess if it had belonged to a man or a woman. Men’s brains are larger, for example, and are likely to have a larger number of “male” features overall. But the new findings suggest that it is impossible to predict what mix of brain features a person is likely to have based on their sex alone.

On a population basis there is a significant difference but any particular individual will have some degree of mixing. However, a small percentage will show significantly less mix which in terms of male violence might be significant.

Social conditioning

The Dunedin Longitudinal Study has shown clear evidence for the interaction of genes and environment.

Some people have testified (there are some fascinating examples inThis American Life episode 220) to experiencing striking changes in mood and behaviour associated with changes in their baseline testosterone level. But individuals vary in their sensitivity to testosterone, so not everyone on hormone treatment will experience these effects as strongly; and, more generally, measured testosterone level is not a good predictor of individual behaviour (as seen in the third story).

I’m just interested in how the mind works, with a particular focus on categories (and the role of story), and think that understanding male power dynamics is critical to dealing with the resurgent threats to liberal democracy.

And I think what we are is in large part the product of our evolutionary heritage which modern science such as brain scans continues to shed light on.

As an aside, the Nouméa Accord plays out in New Caledonia this week with the referendum on independence. Sadly there’s a very real chance that the result may not be respected by the losing side. That could lead to the sort political violence seen in the 80s.

The Accord was supposed to allow time for the development of inter community rapprochement but it seems to have been too difficult.

A prominent Kanak woman politician appears to be not able to take part in the process which is a real tragedy.

From my reading, it appears you are talking about artificial intelligence. The threat, or perceived threat to liberal democracy is more dynamic than just a cohort of men with personality disorders.
